Condensate Remover Installation & Maintenance Manual INSTALLATION

2. The discharge water from the unit MUST flow through the CR330 in the proper direction. See Figure 1, page 4.
a. Screw the 5/8" barb x 1/2" MPT fitting into the inlet, the end with the FEMALE threads of the CR330, as shown in
Figure 1. Slip the 5/8" discharge water line from the unit over the barbs and secure the water line with two 5/8"
stainless steel hose clamps. To prevent the CR330 from moving while underway, secure the water line with two
hold-down clamps. If the CR330 moves, the lines may loosen and leak, causing the boat to flood.
b. Screw the 1/2" x 1/2" coupling onto the end of the CR330 with the MALE threads. Screw the 5/8" barb x 1/2" FPT
fitting into the coupling. Use pipe dope to seal all threaded connections. Slip the 5/8" water line from the thru hull
over the barbs and secure the water line with two 5/8" stainless steel hose clamps. To prevent the CR330 from
moving while underway, secure the water line with two hold-down clamps. If the CR330 moves, the lines may
loosen and leak, causing the boat to flood.
NOTE: Double-clamp all 5/8" seawater hose connections with two stainless steel clamps, reversing the clamps.
CONDENSATE LINE ASSEMBLY
Refer to Figure 1, page 4.
1. Install the 5/8" hose barb x 5/8" fitting into the inlet side of the filter/strain. Install the 1/2" MPT x 1/4" barb fitting into the
discharge end of the filter/strain. Use pipe dope to seal each threaded connection.
2. Cut a 12" (30.5 cm) piece of 5/8" tubing. Connect one end of the clear 5/8" tubing to the condensate fitting on the drain
pan of the air conditioner. Secure this connection with a 5/8" screw-type stainless steel hose clamp. Install hold-down
clamps to prevent the line from moving.
3. Connect the other end of this 5/8" tubing to the inlet side of the filter/strainer. Secure this connection with a 5/8"
stainless steel screw-type hose clamp.
4. Cut a 2-1/2" (6 cm) piece 1/4" clear tubing and connect it to the 1/4" end to the filter strainer. Secure with a 1/4"
stainless steel screw-type clamp. Connect the other end of the 1/4" tubing to the check valve and secure with 1/4"
stainless steel screw-type hose clamp. Install hold-down clamps to prevent the line from moving.
NOTE: The check valve allows water to flow in one direction – from the condensate drain pan into the CR330. To
determine the proper orientation of the check valve, blow into one end of the check valve. If air passes freely through
the valve, this is the correct direction for the water flow.
5. Cut a 7 ft (210 cm) piece of the 1/4" tubing. Connect one end to the check valve and the other end to the CR330.
Secure both connections with 1/4" stainless steel screw-type hose clamps.
SYSTEM TEST
1. Open the seacock or ball valve.
2. Turn the circuit breaker for the air conditioner to the on position. If the water pump has a separate breaker, turn this
breaker on.
3. Lower the temperature set point of the air conditioner so that it is below room temperature and the air conditioner
begins operation and cool air is being produced.
4. With the air conditioner running, pour 2-3 cups (1/2 liter) of clean water into the condensate drain pan of the air
conditioner. The condensate water should begin to immediately flow from the drain pan through the clear hose and into
the CR330.
5. Check all connections to make sure that they are tight and secure.
6. Make sure all lines and tubing are free of kinks.
NOTICE
Water must flow in the proper direction through the filter strainer. On the side of the strainer is an arrow
that indicates the correct direction. Make sure the water flow is aligned with the arrow.
